The latest beauty craze sweeping Hong Kong is the Microneedle Therapy System, which involves massaging the face with a needle-studded roller.

The Hong Kong Consumer Council has issued a warning to users of the device, stating there is no scientific evidence to prove its effectiveness and warning that the device is potentially lethal.

"It is unwise to risk your life for a prettier appearance," Consumer Council publicity and community relations member Philip Leung Kwong-hon told the South China Morning Post.

Users of the Microneedle Therapy System are exposing themselves to a high risk of infection of bacteria, fungi and viruses on the needles, including HIV and hepatitis. The Consumer Council advises that soaking the device in hot water or rinsing it in medical disinfectants is not enough to sterilize the device.
